X-ray imaging apparatus, image processing apparatus and image processing method

Abstract

An X-ray imaging apparatus may include an image acquirer configured to acquire a plurality of X-ray images of an object in different energy bands; and an image processor configured to perform scattering correction on the plurality of X-ray images to remove X-ray scattering from the plurality of X-ray images, perform material separation on the plurality of X-ray images on which the scattering correction has been performed to acquire material information of at least one material included in the object, and repeatedly perform the scattering correction and the material separation depending on whether a predetermined condition is satisfied.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from Korean Patent Application No. 10-2015-0010423, filed on Jan. 22, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND[0002]1. Field[0003]Apparatuses and methods consistent with exemplary embodiments relate to an X-ray imaging apparatus that separates a material using a multi-energy X-ray image, and an image processing apparatus, and an image processing method.[0004]2. Description of the Related Art[0005]An X-ray imaging apparatus is an apparatus that irradiates an object with X-rays and detects the X-rays transmitted through the object to image the internal structure of the object. Based on X-ray attenuation or absorption depending on characteristics of a material constituting the object, it is possible to image the internal structure of the object from the intensity of the X-ray transmitted through the object. However,...

AI Technical Summary

Benefits of technology

The patent describes an X-ray imaging system that can better identify different materials in an object and correct for scattered X-rays using a multi-energy image. This improves the accuracy and reliability of the imaging process. Additionally, there are also image processing tools that can enhance the image quality and make it easier to analyze and interpret X-ray images.

Problems solved by technology

However, materials having similar X-ray attenuation characteristics are difficult to be distinguished from each other in an X-ray image, and in a case of an X-ray projection image, materials overlapped with each other among the constituent materials of the object are difficult to be distinguished from each other.
